Aircraft A has a perfect
automatic flight control system (follows the computed route perfectly) but
uses ground-based navigation that only provides lateral accuracy of a
half-nautical mile (95
%). Aircraft B has a poor autopilot that can only
keep the aircraft within a half-mile of the computed route (95
% of the
time) but uses GPS (that provides lateral accuracy of 2 meters, 95
%).
Which aircraft has a larger Total System Error (TSE)?
